Product Specification

Coal slime High Efficiency Thickener for coal preparation plant

1.Product Introduction High Efficiency Thickener

Designed specifically for coal slime dewatering, this high-efficiency thickening equipment utilizes the synergy of gravity stratification and mechanical scraping to achieve rapid thickening and effective solid-liquid separation. Featuring an inclined tank body and a dynamic scraping system, the equipment supports continuous operation, significantly increasing coal slime concentration and reducing the load on downstream processing. It is ideally suited for modern coal washing and preparation lines.

2.Application High Efficiency Thickener

• Coal Washing & Preparation: Replaces traditional dewatering equipment to raise coal slime concentration to optimal levels, reducing transportation volume and costs for thermal coal, coking coal, and other varieties.

• Resource Recycling: Recovers process water for recirculation within the coal washing flow, lowering fresh water consumption and supporting sustainable production goals.

• Industrial Wastewater Treatment: Extends to chemical and metallurgical sectors for treating high-concentration organic sludge and optimizing solid-liquid separation efficiency.

3.Working Principle High Efficiency Thickener

Gravity Stratification Mechanism

• The coal slime slurry undergoes gravity-driven stratification within the inclined tank. Solid particles slide naturally along the sloped bottom to form a high-concentration sediment layer.

• Clarified water is discharged via the upper overflow weir, achieving primary solid-liquid separation.

Dynamic Scraping System

• A rotating rake assembly moves at a constant speed, continuously scraping settled solids toward the central discharge outlet. This prevents localized accumulation that could impair dewatering efficiency.

• The scraping frequency is optimized to match the tank's inclination angle, ensuring a uniform and stable dewatering process.

Intelligent Control Unit

• Integrated sensors and control systems monitor the concentration gradient within the tank in real-time, automatically adjusting the rake’s rotational speed and lifting frequency.

• The system supports remote monitoring and fault pre-warning, significantly reducing the need for manual intervention.

4.Advantages High Efficiency Thickener

• Optimized Energy Consumption: Utilizing gravity for solid-liquid separation results in significantly lower power consumption compared to traditional mechanical dewatering equipment. The continuous operation mode further enhances overall energy efficiency.

• Increased Concentration: By optimizing the tank inclination and scraping frequency, coal slime reaches higher density levels. This reduces thermal energy loss in subsequent drying stages and lowers overall production costs.

• Environmental Friendliness: The enclosed design effectively suppresses dust emissions, while the overflow water is treated for reuse. Wastewater discharge is drastically reduced, complying with stringent industrial environmental standards.

• Simplified Operation & Maintenance: The use of corrosion-resistant materials and automated controls reduces manual labor and results in a low failure rate. Extended maintenance cycles further decrease operational costs.
